WATCH-CASE.

BPECIFICATEON farming part of Letters Patent No. 313,360, dated March 3,1885.

Application filed June 7, 1884. '(No model.)

'To all whom, it 77mg/ concern:

Be it known that I, DANIEL OHana, of Valtham, in the county ot'Middlesex and State of Massachusetts, have invented certain new anduseful Improvements in Vatch-Cases, ot' which the following is a full,clear, and exact description.

This invention, in substance, consists of a band or ring to contain themovement arranged therein, in the usual or any othersuitable manner,which band is made in one piece with the annulus or central shell orbody, and either of the same or of different metals, or ot' othersuitable material, and either by both being made of one piece or ot'separate pieces permanently secured together, and said central shell isleft open at either its back or its front side, and the open sideclosed, and the ring made with risers at its front and back sides,extericrly adapted for the attachment of other parts ofthe case.

This invention, in substance, also consists ot' a ring or band tocontain the movement, arranged therein in the usual or in any othersuitable manner, whichband is made in one piece with the central annulusor shell, and either ot' the same or oi' different metals or of othersuitable material, and either by both being made of one piece or ofseparate pieces permanently secured together, and said central shell isleft open at either its back or its front side, and the open side closedby a separate piece suitably attached for removal at pleasure, and thering made with risers at its front and back sides, exteriorly adaptedfor the attachment ot' other parts ot the case.

The figures of the accompanying plate of drawings, forming a part ot'this specification, illustrate the present invention, and they are allon a similarly enlarged scale.

Figure l is in part a central transverse section and in part an edgeview of a watch-case with the movement removed. Figs. 2 to 8, bothinclusive, and Fig. l0 are sectional views at one side only ot' awatch-case, and they are all in illustration of the construction ofthecentral shell or annulus and movement ring or band in accordance withthe lirst part ot' this invention, as heretofore stated; and Fig. 9 is asectional view at one side only ot' watch-case in illustration oftheconstruction of the central shell or annulus and movement ring or bandin accordance with the second part ot' this invention, as heretoforestated.

In the drawings, A is the band or ring to contain the watch movement.:Eis the central shell, or annulus or body. C is the front bezel-ring,and D its crystal. E is t-he back bezel-ring, and F its crystal. G isthe front cap or plate. H is the baclrcap or plate.

The movement band or ring A interiorly is adapted in any of the usualways or in any other suitable way for receiving and securing` thewatch-movement. (Not represented in the drawings.) This ring Aexteriorly is sur rounded by the central shell or body, preferably madewith a recess or chamber, J; butit may be made solid, or nearly so,using` a base or inferior metal-such as albata, nichel, brass, or othermetal or material-forthe inner and unexposed portions thereof, and forits exposed sides or surfaces silver, gold, or other precious metalorsuitable material. The central shellor annulus. B, and movement-ring Aare either made ot' one )ieee of metal or ot' other suitable material,or ot separate pieces ofthe same metal or ot' ditt'erent metalsormaterials secured together by solder or otherwise in any suitablemanner, and all so that the same together shall constitute in fact onepiece ofthe case, which, combined with the other parts for theattachment ot' which said shell and ring are adapted. as hereinafterdescribed, will secure the complete watch-case desired.

K and L are risers-one, K, at the front side, a, and the other, L, atthe back side, b, ofthe central shell or body. Each of the risers isexteriorly adapted-the riser K at the front side for the attachment otafront bezel-ring, Figs. l to l0, both inclusive, and the riser L at theback side for the attachment of a back bezel-ring, E, Fig. 4, or for theattachment of a back cap or plate, H, Figs. 2 and 3, and Figs. 5 to l0,both inclusive, and for this attachment of said parts, as particularlyshown in all the figures except Fig. S, a screw-thread, d, is formedexteriorly about the riser for the part it is to receive to be screwedupon it, and, as shown in Fig. S, the riser exterior-ly is left plainand smooth for the front bezel-ring to be snapped over or upon it,instead of being screwed upon it, asshown in the other tigures.

In Figs. 1 to 4, both inclusive, and Figs. 6

IOO

to 9, both inclusive, the back side, f, ot' the central shell is leftopen. and, except in Fi", 3, such open side closed by a separate. rirgpiece or plate, M. which is suitably attached lor removal at pleasure.

ln Fig. 3 the open sidef ot'the central shell is closed by the back capor plate, and no separate ring, M, is shown, and in Fig. 5 the centralslnll or body is continuous t'rom the t'ront side to the back side ol'the ring.

The attachment otl said removable ring M, above referred to, maybe madein various ways-as, for instance, by screwing it over 'and upon theexterior ot' the riser L, bel'ore referred to, at the back side ot' thecentral shell or body, B, or rather movement-ring A.. Figs. 4 and 7, orover and upon a separate riser at the back side ot' the movennnt-ring A,Figs. (i and 9, or by screwing it into and upon the interior ot' theouter part or edge otn the central shell, Fig. 2, or by simply locatinglor setting it within the central shell, shoul` dei-ed, as at g, Figs. 1and S, to make a suitable rest therefor, and thus shoulderiug may becombined with the said adaptation either ot' the central shell or body,or ot' the movement-band, for screwing the said separate ring intoplace; and this separate and detachable ring M may be l'ormed so as toconstitute of itself a crystal bezel-ring, E, Fig. 6, or be constructed,as shown in Fig. 9, to wholly close the movement-ring A at its backside, and in such ease, it' a back cap or plate, H, is desired, saidring M is also provided with a riser, N, exteriorly constructed tor theattachment thereof-as, t'or instance. by making it with a screw-thread.rlhis separate ring M may be adapted to be snapped into place, and thusattached the sameas bezel-rings and capplates ot" watch-cases are nowcommonly attached, or to be otherwise fastened in place. and the samemay be said ot' the l'ront bezel-ring, the back bezel-ring, and thefront and back caps or plates, either or all ot' which may be hinged totheir proper riser.

ln Figs. 6 to 9, both inclusive, the cap or plate is shown as located atthe front side ot" the central shell or annulus, the shell having asuitable riser, P, t'or receiving it, and the attachment ot' said plateor cap may be secured by snapping or screwing it over and upon saidriser, or by liinging it, all as well known, hinging being preferablefor obvious reasons.

W'ith the central shell or annnlus madehollow or chambered, as at J, andleft open at one side, asshown in Figs. 1 to 4, both incitisive, andFigs. 6 to 9, both inclusive, and such Open side closed` as stated, andwith this chamber ot' suitable shape, an opportunity is ait'orded forthe insertion therein and removal therel'rom ot' a case spring` orsprings l'or operating upon either the front or back. or both the t'rontand back, plates, as well known in hunting-\\ateh cases.

The right is hereby reserved to protect by separate Letters Patent theconstruction, substantially as herein described, ot' a ring, M, closingthe open side ot' a central shell or body, B.\\ith a riser, N, l'or theattachment of other parts ot' the ease.

lleretot'ore the central shell or body and mtwement-ring ot a watch-casehave been made in one piece. and the shell constructed t'or theattachmentot' other parts ol' the caseas, t'or illustration, see LettersPatent ot' the United States issued to me, dated Hay 13, 1854. No.298,615. ln the present invention, however, it is the movement-ring andnot the shell which is constructed lor the attachment ot other partsofthe case, and, in view ot' the Letters Patent referred to, this`invention is to be construed as strictly limited to a combined shell andmovementsring having the movement-ring constructed, substantially asdescribed, l'or the attachment ot' other parts ot' the ease.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. ln a watch-ease, a movement band or ring, A. and a central shell, B,constituting one piece, let't open at one side, and the ring A, madewith risers K L, through which to attach other parts ot' the case,substantially as described, for the purpose specilied.

2. ln a atcb-case, a movement baud or ring, A, and a central shell, B,constituting one piece, left open at one side, closed by a separateplate, M, and the ring A, made with risers K L, through which to attachother parts ot' the case, substantially as described, for the purposespecilied.

In testimony whereof l have hereunto set my hand in the presence ot' twosubscribing EDWIN W. BROWN, WM. S. BELLoWs.
